Patent DE-2926697-A1 (DE)
Title: Intermittent fault location in exchange switching fields - analyses accumulated data on connections with less than specified duration
Inventor: SCHOENBERGER KARL WILHELM
IPC: H04Q3/54
Filed: 1979-07-02
Abstract: Intermittent faults in the switching circuits of a computer controlled telephone exchange are located by measuring the time for which a circuit is engaged. It is assumed that faulty circuits are engaged for shorter times than serviceable ones. If the time is less than a specified minimum, the controller checks whether it was engaged with a subscriber. If not, the event is stored together with the circuit identity. The method is extended to the switching fields by using another store to accumulate similarly determined faulty switching data. At intervals, the store contents are read out and analysed to determine which elements are most often involved.

Title: Tone signal generator for telephone exchange - has circuit which can be connected to one or more subscribers as required and ordered by central controller
Inventor: RUDOLPH HELMUT
IPC: H04Q3/52
Filed: 1980-03-01
Abstract: The tone signal generator (TOS) can be connected to the connecting network (KN) and to individual subscribers. The basic generator produces a continuous tone which is modified as required by switching to produce the necessary signals, for example the calling and engaged signals. For this purpose the generator is connected to a sub-network in which the switching takes place. From the sub-network the tone signal system (TOS) can be connected as required to one or more subscribers (TS) by means of a controller (TSW) which is subordinated to the exchange controller (ZST). The switching of the tone generator to its sub-network is timed so that the generator is never short circuited. This is achieved by having pauses between the two switching functions necessary for operation. The circuit gives increased utilisation of the exchange connecting network. The application is to electronically controlled telephone exchanges.

Title: Electrode assembly for simultaneously machining parallel holes - uses electrode rods located by hydrostatic pressure in a common gland box
Inventor: DIBATTISTA DANTE PHILIP
IPC: B23H7/26
Filed: 1980-10-01
Abstract: The electrode mounting is for a spark erosion machine tool which produces several holes in a workpiece in one operation. The object of the proposed electrode mounting is to permit easy adjustment for wear after each operating cycle. The electrodes (24) pass through a common gland box (36). Each electrode passes through an individual hole (40,42) in opposite faces of the box, and is surrounded by gland bushes (48,50) in each hole. An insulating flexible sleeve (32) electrically isolates the electrode from the box. It also acts to transfer hydrostatic pressure from a fluid inside the box (38) to a loose segment (58) in one of the bushes (48). With the pressure high the segment (58) presses against the electrode (24) locking the latter against axial movement. After a machining operation the wear on the electrodes will be uneven. The pressure is then reduced which releases the clamping force on the electrodes which can then be repositioned.

Patent DE-3049250-A1 (DE)
Inventor: MALLEK HEINZ
IPC: C10B53/00
Filed: 1980-12-27
Abstract: Separation of the apparatus for drying and degassing organic waste from the shaft furnace containing a gasification chamber and a combustion chamber increases the through-put capability of the shaft furnace gasification. The gasification is promoted by the addition, in the same direction of flow as the partly carbonized waste material, of a gas such as air, steam, carbon dioxide or oxygen adjusted in accordance with the changes in composition of the material that is gasified. The drying and degassing chamber is a rotary drum feeding the dried and degassed material into the top of the shaft furnace. An intermediate chamber may be imposed between the rotary drum and the shaft furnace at the top of the shaft furnace so that a sieve can separate incombustible material such as metal parts for withdrawal through a gas-tight sluice. A narrow gap, either a straight gap between moveable members or an annular gap defined by a rotary plug, provides the communication between the gasification chamber and the combustion chamber below. Material is held above the gap for completion of gasification and the actual combustion with additional air supply takes place in the combustion chamber.
